Staal & Plast polystyrene adhesive – for EBB & Flow trays

Staal & Plast Polystyrene Glue is a professional adhesive specially developed for assembling, extending and repairing EBB & Flow trays made of high-impact polystyrene (HIPS). The formula is made from the same material as Staal & Plast trays, ensuring an exceptionally strong, waterproof and durable bond between individual components. Suitable for both new installations and repairs to professional irrigation systems.

Staal & Plast Polystyrene Glue is specially developed for the manufacturer's professional EBB & Flow systems and ensures a reliable, durable bond between the individual trays. Unlike universal adhesives, it contains high-impact polystyrene (HIPS), identical to the material used to make the trays themselves. This allows the materials to bond as one, creating a strong, watertight connection.

When building large EBB & Flow tables, the manufacturer recommends initially securing the trays with hot melt glue to ensure correct positioning and the required installation gap. Then use the polystyrene adhesive to permanently bond the trays together and create a strong joint.

The adhesive is suitable for both new installations and repairing damaged trays. Once fully cured, it forms a strong, durable bond that withstands constant contact with water, nutrient solutions and the usual conditions in greenhouses and professional production facilities.

The manufacturer recommends applying the adhesive evenly and sparingly. Excessive amounts can damage the trays, and such damage is not covered by the warranty.

📋 Instructions for use

1. Align the trays and leave the recommended installation gap.
2. Temporarily secure them with hot melt glue, if necessary.
3. Apply an even layer of polystyrene adhesive along the entire length of the joint.
4. Allow the adhesive to cure for 48–72 hours at around 20°C.
5. Do not use or fill the system with water until the adhesive has fully cured.

⚠️ Important: Do not apply too much adhesive. Excess adhesive can damage the trays, and such damage is not covered by the manufacturer’s warranty.

💡 Tip from Urban Botaniks: When building large EBB & Flow tables, use the original Staal & Plast adhesive. Because it is made from the same HIPS material as the trays, it creates a strong, durable bond that can withstand daily use and constant contact with water and nutrient solutions.
